From: Thomas J. Linscomb <linscomb@ut-ngp.ARPA> Some of the DMF-32 look-alike boards (i.e. ABLE VMZ-32 and -32/N) have problems under VMS v4.0. The symptoms are that the terminal will show a "device timed out" via SHOW TERMINAL and auto-bauding will not work. This occurs because of line garbage and the fact the look-alike boards do not exactly emulate all the XON and XOFF features of the DMF-32. Some sites had no problems during field test while others were totally disabled by this problem. It was usually caused by noisy modem lines. There are three methods to fix this problem. ABLE is looking to distribute (probably for a price) roms that will fix the problem in their boards. Also VMS version 4.1 fixes the problem by disabling some of the functionality of the YCDRIVER. Look in the Release Notes for VMS v4.1 under the patches to the YCDRIVER to find out how to solve this problem via software. I have also heard that there is a non-DEC patch that will solve this problem. ---------- Thomas J. Linscomb aka linscomb@ut-ngp.arpa The University of Texas Computation Center
